We now have a dream team to find a path for a public release of the A5 jailbreak.

Cross your fingers.

The only issue is of Sandbox.

Sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers, untrusted users and untrusted websites.

The sandbox typically provides a tightly-controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In this sense, sandboxes are a specific example of virtualization.

The team is now working hard to read/write the files at the correct place on the iDevice, so they can place the right files at the right place. After they are done with the Sandbox thing, the release of Untethered Jailbreak will be made imminent. The Untethered Jailbreak is said to be coming for the new iOS 5.0.1 for iPhone 4S and iPad 2. So update your iDevices now before it is too late.
